Good thread but it dosen't answer all my questions.
I have an Enermax Noisetaker 420w (+12v, 15/14A dual rails; +3.3, 32A; +5, 36A).
29A's on the 12 rail - you might think that is enough!(especially when the so called king of PSU's the Antec True 550w only offers 32A i beleive!)
But - I am having all sorts of problems oc'ing my new 939 rig and it is always the addition of extra drives / fans that cause things to change.
Here's my question - Are dual rails bad for overclocking as they limit the power to the CPU and Mobo. For example - maybe my mobo is drawing 18A's and my CPU only 8A's, which combined is 26A's and well within the PSU's limits but, from this example my MOBO is underpowered as the rail only extends to 15A's! (This might be a bad example as I'm no expert on power - but you get where I'm coming from - yes?)
Point is if I didn't have dual rails I would have enough power for my example - period - but with dual rails I would be underpowered - right?
So - Are dual 12v rails bad for large output systems as they are inflexible.
Another guy had the same problem with Enermax 480 and switched to Tagan 480, which has 28A on the 12v (less than his enermax combined rails) BUT he is now rock solid as there is no splitting of the rails).
Help someone please - also this will make this thread very comprehensive if it including a section on dual rails.
Cheers all.
